Establish a parameter in a configuration file or an environment variable such that at application start you read it and use its value to determine how to display the currency.
Design an application in such a way that if the parameter is not found, you show money values without a currency symbol.
we (developers) only have one shot at making a favorable first impression
Above is right, but this simple fact of life should inspire your creativity, not inhibit it.

would you prefer it the other way?
- (customer) well, let's try it that way first
- okay - see how it works. Anything else?
- you said you can show money values the other way,
can you show them as "USD"?
- sure, one minute. Okay - see how it works with "USD". Anything else?
- so far so good, can you show money values without a currency symbol?
- sure, one minute. Okay - see how it works that way. Anything else?
- when can I have it?
